Error 51: Expecting Function Name
PostPosted: Mon Aug 12, 2019 1:32 pm     Reply with quote

Hi, I've been trying to compile this code but I don't know what's wrong.
I have reviewed it a thousand times and have not yet been able to find
the solution. I hope you help me please.

1) Use the code buttons when posting code. Otherwise it becomes very
hard for us to read.
2) It looks like you have almost all your code inside an interrupt handler.
Don't.
Interrupt handlers should be short and quick. No complicated maths,
no delays, etc. etc.
3) The actual error though is caused by lcd_putc. You have a variable called
'lcd_putc', no function of that name. You are then trying to use this in
printf, where a function name is expected.

You get this error when you are missing the main() function.
In CCS, you must have a main() function.

Excuse Ttelmah
I have the similar problem with a code, and I don't understand what do you mean with "You are then trying to use this in printf, where a function name is expected", Could you help me?

other problem...
Quote:
i = (i/120)*2800; // corriente del secundario del sensor

You've declared 'i' as 'int', which in CCS C is int8 or 8-bit, NOT 16-bit which I think you think it is.
The same holds true for other variables.

Look at the CCS example file Ex_lcdth.c in the CCS Examples folder.
It shows this line:
Quote:
printf(lcd_putc,"\fCurrent Temp: %U F\nMin: %U Max: %U", current_temp,min_temp,max_temp);

This line sends the output of the printf function to the lcd_putc() function.
This feature is an extension of the C language provided by the CCS
compiler. It's useful. You can send the output of printf() to any function
that accepts a character as input, such as lcd_putc().

Note that the Ex_lcdth.c file includes the lcd.c driver in it. This file has
lcd_putc() defined in it:
Quote:
#include <16F887.h>
#use delay(crystal=20mhz)

#include <lcd.c>

Ttelmah means that he is missing the #include <lcd.c> line, so lcd_putc
is not defined.
